The art style for Gardenarium looks trippy as hell and wonderful. Music sounds great as well. This will be my weekend experiment.

$5 Mac, PC, Linux.

Update:

The appeal of the game is in its visual aesthetic and whimsical characters. Occasionally set pieces are very dramatic (climbing the mountain to consult with that guru from the trailer, for example) but I had trouble figuring out where I was supposed to be. The first person you meet in the game satirically tells you that "your one and only objective is to win" - tacitly asking the player to cast aside this goal oriented thinking - but after the impact of the games psychedelic visuals wore off I found myself losing focus.
